SPECIFICATION forming part of Letters Patent No. 399,200, dated March 5, 1889.

Application filed June 1 8, 1888.

To all whom it may CON/067721.

Be it known that 1, CHARLES F. KOEHLER, a citizen of the United Qtatcs, residing in the city ot St. Louis, in the State oi Missouri, have invcntctl a new and usct'ul lmprovei'nent in Apymratus tor the Pastcurizatiou of Beer, of which the following is a specification.

My invention relates to improvements in the mode of introducing steam into the steaming-vats, in which the bottles tilled with beer from the brewery are placed and covered with cold water, and then subjected to heat by introducing steam into the vat containing the bottled beer and water and heating the contents to a sutticient degree to destroy the yeast molecules in the beer contained in the bottles and arrest fermentation, thus bringing about that condition of the beer called pasteurizat-ion;" and the object of my invention is, first, to provide a continuous distribution of the heat throughout the water from the top downward, thus saving breakage; second, to afford facilities for obtaining an equalization of the heat of the water and bottled contents of the vat; third, to reduce the amount of the surface of steam-pipe heretofore used and dispense with the holes or perforations therein; fourth, to insure the direct contactof every part-0t the water in the vat to the steam-supply. ism illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the vat for steaming bottled beer, with a portion of one side broken away, showing my invention fastened in its place in the vat and connected with the steam-supply; Fig. 2, a perspective view of the receiver and distributor as it appears when ready for use; Fig. 5, a vertical view, in cross-section, of the receiver and distributor, showing its operation; Fig. 4, a cross-section of the top or cap of the receiver and distributer through line ii, 3; Fig. 5, a modified detail of a top or cap of the machine, and Fig. 6 another form or modification of the same.

Similar letters and figures refer to similar parts throughout the several views.

The vat or tub A, being placed in a convenient position in the bottling-room, constitutes the frame-work of the machine. The steamsupply pipe Cl is led from the boiler over the I attain these objects by the mecha-nerial No. 277,471. (No model.)

sides and ends ol the vat A and passes down its inside wall to the bottmh, and thence to the middle of the vat, where it is provided a small piece of pipe, :1, it om whence the steam is discharged into the receiver at a point a short distal'lce below the opening-17 in the receivcr-supports d. Directly over and around the vertical section ol the steam-pipe a placed the receiver and distributor, which consists of the socket D, provided with the legs or standards (1, having openings d between. This socket is secured to the bottom of the vat A by bolts, nails, screws, or otherwise. The upper part of the tube 15 is provided at its upper end with an. outer tube or collar, 1), which is snugly titted over and around the tube B, and has a vertical slot, l), regulated. by a pin or set-screw, U permitting of vertical adjustment of the machine to an y desired height.

C is the deflecting and distributing cap or top of the machine. This cap fastened to the outer top tube, 1), and has the openings or open spaces 0' and standards c, whereby the heated commingled water and steam from the steam-supply is thrown outward on all sides in the direction of the arrows show-n at. 4.4, Fig. 3, and thence it takes a downward course, converging toward the openings d in the ma- E chine-socket, where it is again placed in con tact with the steam-supply jet and again heated and distributed as before, repeating the operation until the whole mass of water and vat contents have reached the desired temperature.

The mode heretofore employed in pasteuriz-ing bottled beer was to run a steam-pipe, provided with holes to permit of the escape of the steam of the pipe into the vat, all around it at the bottom. The pipe was rapidly worn. out and rendered unfit for service from the rapid corrosion of the iron around the holes in it. It is apparent that that sysl tem required much more piping than is necessary with the use of my machine, and the steam arising therein from the bottom of the tub attacked the bottles at their weakest j and most vulnerable point-viz, the bottom where the heat was greater than at the upper portion. All of these annoyances and ex:

with an elbow, to which is vertically attached 10 cured to the vat-bottom, and a deflecting-cap supported over openings at the top of said pipe in conjunction with a steam-supply pipe having its opening or discharge immediately below the lower openings in the center of said stand-pipe, all substantially as shown and 15 described, and for the purpose specified.
